the interfemoral membrane. The dentition is IŁ C-J- Pm-J- Mf,
with another upper incisor in the young. It is African, Asiatic,
and Australian.
This genus appears to be connected with Vesperugo by Mr.
Dobson's proposed genus, or sub-genus as it is generally held to be,
Scotozous? The genus Nycticejus, founded for the inclusion of
Scotozous dormer i, an Indian species, should, according to Dr.
Blanford, replace on grounds of priority the name Scotophilus.
But as this name {Nyctieejus) is one introduced by Kafinesque,
whose work was so uncertain and untrustworthy, it seems prefer-
able to retain the better-known name of Scotophilus, introduced
by William Elford Leach.
The genus Chalinolo'bus2 has short, broad ears with an
expanded tragus. A distinct fleshy lobule projects from the
lower lip on either side of the mouth. The tail is as long as the
head and the body. The dental formula is I § C -J- Pm -f or ^ M f.
The genus occurs in Africa, Australia, and IN"ew Zealand; but the
African species, with diminished premolars and pale coloration,
have been distinguished as Glaucowycteris.
Fam. 4. Emballonuridae.—The Bats belonging to this family
have no nose leaf. The tragus is present, but often very small.
The ears in this family are often united. There are two phalanges
in the middle finger. The tail is partly free, either perforating
the interfemoral membrane and appearing upon its upper surface,
or prolonged beyond its end. The face is obliquely truncated in
front, the nostrils appearing beyond the lower lip.
Embcdlonura, is Australian, Oriental, and Mascarene in range.
The ears arise separately, and there is a fairly developed and
narrow tragus. The tail perforates the interfemoral membrane.
The dental formula is I f C ^ Pm |- M f.
Hhinopoma, has the ears united; the incisors are reduced by
one on each side of each jaw, and the premolars are similarly
reduced, but only in the upper jaw.
Noctilio is an American genus of two or three species, which has-
one pair of markedly large upper incisors, which completely con-
ceal the outer pair. On these grounds this Bat was removed from
• its allies and placed by Linnaeus among the Kodents, an instance
of the disadvantage of the artificial scheme of classification. The
species named N. leporinus has been shown to feed upon fish,
